This has been covered in terms of helping the issue of failing old style injectors. My question is: does this have to do with the entire electrical schematic of the old style? Meaning, the ECU, Harness AND injectors? I have a 1990 ECU and harness with new style injectors wired in. Thus, I still have 12v being supplied to my new style injectors, due to old style harness and ECU? Or I'm all set because the 12v supply has been cured by using new style injectors? This is where I fail to see the conclusion. THANKS!!!!
